1994 Chevrolet Suburban SERVICE BRAKES, HYDRAULIC

THESE 3 CASES OF AN ABS FAILURE OCCURRED ON DAMP ROADS. TWO CASES INVOLVED THE RIGHT FRONT TIRES BEING OVER LEAVES ON THE ROAD WHEN BRAKES WERE APPLIED. ALL THE CASES INVOLVED TRYING TO STOP AT A STOP SIGN. NORMAL PRESSURE(NOT A PANIC STOP) WAS APPLIED TOBRAKES, AND ALL 3 CASES WERE AT A SPEED OF 5MPH OR LESS. WHEN THE ABS SYSTEM KICKED IN, THE CAR BASICALLY WOULD NOT STOP WITHIN ANY REASONABLE DISTANCE. WE HAVE HAD PROBLEMS WITH THIS ABS SYSTEM(KELSEY-HAYES) EVER SINCE WE PURCHASED VEHICLE IN 1994. THE PROBLEM IS THAT THIS SYSTEM DOES NOT WORK!!!! IF THE ABS EVER KICKS IN, YOU ARE IN TROUBLE. WE HAVE HAD ONLY 1 ACCIDENT SINCE 1994(CAUSED BY THE ABS), BUT HAVE HAD NUMEROUS NEAR-MISSES. I HAVE EVEN LOOKED INTO DISCONNECTING THE ABS, BUT THERE IS SIOME INTERLOCKING OF THE ABS TO THE TRANSMISSION OR OTHER SYSTEMS THAT PREVENT YOU FROM DOING THAT. I HAVE TALKED TO THE DEALERS, MANUFATURER, AND THE NTHSA. THE DEALERS AND THE MANUFACTURERS ARE NOT GOING TO DO ANYTHING ABOUT IT BECAUSE IT WOULD INVOLVE REPLACING THE WHOLE KELSEY-HAYES SYSTEM NOT JUST A MODIFICATION.*AK

UPON MAKING A GRAUDAL STOP OR WHEN ATTEMPTING TO MAKE A LEFT OR RIGHT HAND TURN ON WET OR DRY PAVEMENT, VEHICLE WENT INTO A SKID, CAUSING EXTENDED STOPPING DISTANCE. CONSUMER HAS CONTACTED DEALER, AND DEALER WAS UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. PLEASE PROVIDE ANY FURTHER DETAILS. EA95-026.*AK

ABS IS MALFUNCTIONING, CAUSING POOR BRAKE PERFORMANCE, AND ABS WILL ACTIVATE ON DRY PAVEMENT.*AK *SLC

ONGOING PROBLEM WITH ABS FAILURE; WHENEVER BRAKES ARE APPLIED IN A SUDDEN/EMERGENCY SITUATION ABS WOULD BRIEFLY ENGAGE, AND THEN RESUME THIS PROBLEM. ALSO, CAUSES LOSS OF BRAKES. PLEASE PROVIDE FURTHER DETAILS. *AK

IN DRY ROAD CONDITIONS ON I-5 NORTHBOUND WE NOTICED THAT TRAFFIC WAS STOPPING AHEAD OF US AND APPLIED BRAKES. WE HAD ALREADY SLOWED TO APPROX 50MPH BEFORE BRAKING . THE VEHICLE NOSE DIPPED AS WE SLOWED TO STOP, THEN THE ANTI LOCK MECH RELEASED THE BASE BRAKES AND WE WERE THROWN UPRIGHT AS WE CONTINUED FORWARD INTO THE CAR AHEAD OF US AFTER A CONSIDERABLE DISTANCE DURING WHICH TIME WE WERE AWARE THAT WE WERE NOT BEING SLOWED BY THE ANTI- LOCK SYSTEM. WE HAD NOTICED THAT THE BRAKES HAD AN UNUSUAL STOPPING DISTANCE IN THE PAST, BUT BELIEVED THAT THIS WAS NORMAL AS WE WERE TOLD BY OUR DEALER. THE BRAKES HAD RECENTLY BEEN SERVICED IN DECEMBER. THERE IS NO QUESTION THAT WE SHOULD HAVE HAD AMPLE DISTANCE FOR ANY PROPERLY WORKING BRAKE SYSTEM TO STOP US IN TIME. *AK

THE TRUCK HAS POOR BRAKING ABILITY, WHICH MAKES IT DIFFICULT TO STOP WHEN NEEDED. ONE ACCIDENT HAS RESULTED AS DESCRIBED, IN 3/1999. MULTIPLE COMPLAINTS AND SERVICE ATTEMPTS HAVE BEEN DONE WITH NO RESULT. MULTIPLE COMPONENTS HAVE BEEN CHANGED AT MY EXPENSE, WITH NO CHANGE. THE DEALER (JOE HOLLAND IN CHARLESTON, WV) STATES THE BRAKES ARE FUNCTIONING AS DESIGNED. THE TRUCK IS VERY DIFFICULT TO STOP IN SITUATIONS WHERE A QUICK STOP IS NEEDED. THE PROBLEM HAS BEEN CHRONIC SINCE THE CAR WAS PURCHASED. IT TAKES A LONG TIME TO SLOW THE CAR DOWN. MANY CLOSE CALLS HAVE HAPPENED. POOR BRAKE PERFORMANCE.*AK

EA 95 026/POOR BRAKE PERFORMANCE: WHEN APPLYING BRAKE IN A SUDDEN STOP/EMERGENCY SITUATION IT CAUSES LOSS OF BRAKING, AND VEHICLE CONTINUES ON. DEALER NOTIFIED ,AND INFORMED CONSUMER THAT NOTHING COULD BE FOUND. PLEASE FELL FREE TO PROVIDE ANY FURTHER DETAILS. *AK

WHILE MAKING A SUDDEN STOP BY DEPRESSING BRAKES VEHICLE WOULD EXPERIENCE EXTENDED STOPPING DISTANCE. PLEASE PROVIDE FURTHER INFORMATON. *AK

ON SEVERAL OCCASIONS THE ANTI LOCK BRAKES HAVE NOT ALLOWED THE VEHICLE TO STOP. THE LAST OCCASION RESULTED IN A REAR END COLLISION ALTHOUGH THERE WAS PLENTY OF ROOM TO STOP IF THE BRAKES HAD WORKED PROPERLY. THE LOCAL CHEVROLET DEALER IS OF NO HELP BECAUSE THE BRAKES FAIL SPORADICALLY AND THEY HAVE NOT BEEN ABLE TO DUPLICATE THE PROBLEM AND THE COMPUTER TEST SHOWS NO DEFECT. I HAVE CONTACTED GM TO COMPLAIN AND THEY HAVE AN OPEN FILE ON THIS (NO. 990468281) BUT HAVE NOT OFFERED ANY ASSISTANCE. THIS IS A DANGEROUS CONDITION WHICH THE DEALER AND MANUFACTURER ARE IGNORING. THE ANTI LOCK SYSTEM ON THIS VEHICLE NEEDS TO BE REPLACED. *AK

ON RAINY DAY WENT TO SLOW DOWN, BRAKE PEDAL MADE CLICKING NOISE AS I APPLIED PREASURE. THEN IT WENT TO THE FLOOR AND VEHICLE MOVED FOWARDS INTO THE BACK OF A STOPPED CAR AT A TRAFFIC LIGHT. A MECHINC AT SEARS GARGE SAID HE THOUGH THE 1994,S AND 1995,S HAD PROBLEMS WITH ABS SYSTEMS. I WOULD LIKE TO KNOW HOW MANY OTHER ACICIDENTS HAVE OCCURED SINCE 1994 INVOLVING ABS SYSTEM ON SURBUBANS? THANK YOU. *AK

INTERMITTENTLY WHEN BRAKES ARE APPLIED UNDER NORMAL BRAKING CONDITIONS, PEDAL GOES TO THE FLOOR, RESULTING IN EXTENDED STOPPING DISTANCE. *AK

ABS OVER RIDE DOES NOT STOP VEHICLE, RUN INTERSECTIONS, CROSS LANES OF TRAFFIC, LOST CONTROL. *AK

WHEN CONSUMER APPLIED BRAKES BRAKING SYSTEM LOCKS UP AND RELEASED STOP AND REPEATS THE CYCLE.*AK

BRAKE DISENGAGED, VEHICLE COASTED FORWARD, REAPPLIED THE BRAKES AND CAR BRAKED PROPERLY, SOMETIME IN DAMP WEATHER AFTER A LONG PERIOD OF SITTING THE BRAKES GRABS VIOLENTLY.

WHILE DRIVING AT ANY SPEED CONSUMER STEPPED ON BRAKES, AND COULD FEEL VIBRATION FROM THE FRONT. ALSO, EXTENDED STOPPING DISTANCE. *AK

VEHICLE EXPERIENCED PROBLEM WITH ABS BRAKING SYSTEM WHICH CAUSES FOR POOR BRAKING ABILITY. NLM

ABS BRAKE SYSTEM HAS ACTIVATED AND CREATED A DANGEROUS SKID ON AT LEAST 6 OCCASIONS. I AM AN EXCELLENT DRIVER AND USED AVOIDANCE MANOVEURS TWICE TO AVOID COLLISIONS. THERE SEEMS TO BE TWO CONSISTENT CONDITIONS THAT CAUSE THE ACTIVATION OF THE ABS /SKIDDING...BUMPY ROADS(I HAVE SKIDDED BOTH ON DRY RAILROAD CROSSINGS AND DRY UNPAVED MOUNTAIN ROADS) AND,SECOND, RAINY PAVED SURFACES THAT WOULD NOT ORDINARILY INDUCE A SKID. WET WHITE PAINTED LINES AT INTERSECTIONS ARE MAJOR CONTRIBUTORS. WHAT I CANT UNDERSTAND IS THAT AS OF 01/04/2000, YOU ALREADY HAVE 463!!! REPORTS ON YOUR WEBSITE OF THIS VEHICLE/YEAR/SYSTEM FAILURE AND YET, NO RECALL. *AK

WHEN BRAKES ARE APPLIED IN A HURRY IT CAR GATHERS SPEED--HAVE HAD THIS HAPPEN 5 TIMES--TAKEN IT TO DEALER 5 TIMES--4TH TIME THEY SAID LEAKY BACK SEAL--BEFORE THAT THE DEALER SAID NOTHING WAS WRONG..5TH TIME I REAR ENDED A VAN- ALMOST LIKE NO BRAKES AT ALL. NO I WAS NOT PUMPING THE BREAKS! I WOULD LIKE TO KNOW IF THIS HAS HAPPENED WITH ANY OTHER CHEV. SUBS. THANK YOU FOR YOUR HELP. *AK

BRAKES DO NOT WORK WHEN HITTING A BUMP AND APPLYING BRAKES AT SAME TIME. HAS TAKEN AUTOMOBILE TO DEALER, AND THEY SAID THEY CANNOT FIND ANYTHING WRONG. *AK *ML

ABS ON CHEVROLET, SUBURBAN IS UNRELIABLE AND FAULTY - NEED A SOLUTION BEFORE A FATALITY OCCURS.*AK

TRAVELING AT 30MPH THEN HAVING TO MAKE A SUDDEN STOP DUE TO TRAFFIC CONDITIONS, THE BRAKES WERE APPLIED WITH FULL FORCE. A VERY LOUD GROWLING NOISE WAS HEARD FROM THE ABS BRAKING SYSTEM AND THE VEHICLE DID NOT STOP, NOR DID IT APPEAR TO SLOW DOWN. THE RESULT WAS COLLISION DESTROYING THE VEHICLE THAT WAS REAR-ENDED.

ABS PROBLEMS; WHEN APPLYING THE BRAKES THE TRUCK DOES NOT HAVE ADEQUATE STOPPING POWER, WHICH INCREASES THE STOPPING DISTANCE. THIS HAPPENS ON ANY TYPE OF ROAD SURFACE. THE PROBLEM HAS BEEN REPORTED TO THE DEALERSHIP. ALSO, BRAKE PADS WERE REPLACED THREE TIMES, ROTORS WERE TURNED BECAUSE OF WARPING. PROBLEMS WITH THE ABS CONTINUES. PLEASE PROVIDE ANY FURTHER INFORMATION. *AK

NO SUMMARY LISTED FOR ABOV EVEHICLE. *AK

AFTER INVESTIGATING THIS DEFECT I AM APPALLED THAT THERE HAS NOT BEEN A RECALL. I APPLIED THE BRAKES AS I NORMALLY DO WHEN APPROACHING A RED LIGHT. THE CAR BEGAN TO SLOW DOWN AND THEN ALL OF A SUDDEN THERE WERE NO BRAKES. I WAS TOLD BY THE DEALER (THEY DID A TEST AND THE SAME THING HAPPENED WITH THEM, THE VEHICLE NOT STOPPING UNTIL 30-35 FEET AFTER THE BRAKES WERE APPLIED) THAT THE ABS SYSTEM IS FUNCTIONING PROPERLY ACCORDING TO GM. UNBELIEVABLE! *AK

EA 95 026/POOR BRAKE PERFORMANCE: WHEN APPLYING BRAKE IN A SUDDEN/EMERGENCY SITUATION AND A WET/DRY ROAD CONDITIONS, IT CAUSES FRONT WHEEL TO SQUEAL AND LOCK UP. DEALER NOTIFIED. *AK
